Set of 4 double bass strings, medium gauge, Pirastro Perpetual E (2.10m) + ADG. Used for about a year and a half. * E string 2.10m extension Non-smoking environment, no pets. There is some fraying on the felt at both ends, but no bending or breakage at the contact point with the bridge. I think they can still be used. These are standard jazz strings, but I think they can also be used for wind bands and other genres. #DoubleBass #WoodBass #DoubleBassStrings #DoubleBass #WoodBass #EvahPirazzi #DoubleBassStrings #WoodBassStrings
